M771 Internal IOT Decoder

Summary The M771 module is a hardware component designed for the PDP-15 computer. Its primary function is to provide combinational logic circuitry to decode bits 6 through 13 of Input/Output Transfer (IOT) instructions. The document provides technical specifications for the module, including a table of input connections and their associated TTL unit loads, output drive capabilities (10 unit loads for most pins, 7 for pin P1), and power requirements (5V at 74 mA).
